So, I finally found the cure to the silver Sharpie on the black leather sectional. It's called Leather CPR and you can get it at Bed Bath & Beyond for $12. You simply apply it with a clean sponge. I did have to scrub it with the coarse side "lightly" where the marker was. However, to do the entire 7 seat sectional, it took me about 45 min. to condition it. So not only did I get the marker out, but the couches look brand new! And unlike the other postings, I have posted the before picture (in the blog below this one) and an after picture here. I hope this has helped.

But word of advice before trying anything on your furniture, you should ALWAYS try it on a small piece of the couch, like the bottom or somewhere you wouldn't notice if it messes it up.

I tried the advise of Xyko. It worked great and immediately. I used Off Sportman Bug Repellet. I sprayed a small amount on a paper towel and the marker came off immediately. After that I put a leather conditioner on it to remove any residue. So happy it worked, our furniture is brand new. Also it has saved my husbands life. Ha!
